Code P1173 Audi Description
The P1173 diagnostic trouble code (DTC) for Audi vehicles indicates a problem with the Throttle Actuation Potentiometer Signal 2 being too high. The throttle actuation potentiometer is a component of the throttle body that measures the position of the throttle plate and sends signals to the engine control module (ECM) to adjust the air-fuel mixture for optimal engine performance. When the signal from the throttle actuation potentiometer 2 is too high, it means that the voltage output is above the expected range, indicating a potential issue with the sensor or its wiring.
